Quantitative bottom pouring device used for molten tableting

Abstract

The invention relates to a quantitative bottom pouring device used for molten tableting. The device comprises a pouring ladle assembly, a plunger assembly and ejecting and resetting assemblies; the ejecting and resetting assemblies are arranged on the two sides of the pouring ladle assembly, the plunger assembly is arranged above the pouring ladle assembly through the ejecting and resetting assemblies, the ejecting and resetting assemblies are in drive connection with the plunger assembly, the pouring ladle assembly comprises a tundish, and multiple runners are arranged on the bottoms of the tundish. The plunger assembly comprises multiple plungers corresponding to the runners, when the ejecting and resetting assemblies drive the plungers to be ejected, the gaps between the plungers and the runners are opened, molten metal in the tundish is casted, and when the ejecting and resetting assemblies drive the plungers to be reset, the gaps between the plungers and the runners are closed, and the molten metal in the tundish is stopped from casting. Production safety, casting ingot quality and the production efficiency of molten tableting are improved.

Description

technical field [0001] The invention relates to the field of high-temperature molten metal casting ingot making, in particular to a quantitative bottom injection device for molten ingot making. Background technique [0002] Metal ingot is an important auxiliary material for catalysis or deoxidation of molten steel in steelmaking plants. At present, most enterprises use the method of pouring high-temperature molten metal into a mold to make ingots. However, this method of ingot production faces many technical difficulties. The temperature of the molten metal in the tundish is too high to cause oxidation of the metal or the temperature is too low to cause poor fluidity of the molten metal; if the flow channel design is unreasonable, the flow channel mouth will have flashing edge; if the pouring method is unreasonable, it cannot Quantitative pouring leads to uneven weight of ingot products; if the pouring trajectory is too long and the pouring point is unreasonable, resulting i...
